Active clinical trials for "Sleep Apnea Syndromes"

Introduction: There is currently no long-term study, which compares the outcomes of partial tonsillectomy to conventional tonsillectomy. We hypothesize that there will be little significant tonsillar regrowth with partial tonsillectomy. Background and Significance: Tonsillectomy is the most common major surgical procedure performed on children in the United States with nearly 300,000 procedures performed each year, primarily for the indication of obstructive sleep disordered breathing (OSDB). Conventional (total) tonsillectomy removes the tonsillar capsule, and partial tonsillectomy preserves the capsule by shaving away the tonsils using an endoscopic microdebrider. Partial tonsillectomy results in less pain, fewer days to normal activity and diet, and fewer days of analgesics than total tonsillectomy. There are no significant differences between the techniques in blood loss or postoperative life improved Historical evidence suggests that eventually there will be tonsillar regrowth with partial tonsillectomy. However, in a 2003 follow-up report of 243 children undergoing partial tonsillectomy and 107 undergoing complete tonsillectomy from 1998 through 2002 for OSDB there was no evidence of significant tonsillar regrowth. (1) We will follow-up children undergoing partial or complete tonsillectomies at the Cleveland Clinic from 1998 through 2002. There will be standardized tonsillar examinations by two observers, with a third observer in cases of significant disagreement, and questionnaires evaluating sleep apnea and daytime sleepiness, and number of tonsillar infections. If there are a large number of children with recurrent tonsillar symptoms post partial tonsillectomy, the procedure should be abandoned. However, if follow-up reveals comparable tonsillar symptoms for partial and the total tonsillectomy, perhaps the partial procedure should replace the total tonsillectomy as the standard operation to relieve tonsillar OSDB. This could eventually result in millions of less lost days of work and school in the United States.

The purpose of this study is to test whether Spironolactone can improve the severity of obstructive sleep apnea and improve cardiovascular biomarkers in people who are not regularly using their Positive Airway Pressure (PAP) therapy.

A growing number of children with obstructive sleep apnea syndrome (OSAS) or nocturnal alveolar hypoventilation syndrome are treated with continuous positive airway pressure (CPAP) or nocturnal non-invasive ventilation (NIV) therapy. The compliance of the child and his caregivers with CPAP / NIV therapy may be challenging. The use of an educational game (Yapouni) aims at improving communication around CPAP / NIV between the child and his caregivers, and may facilitate the compliance with CPAP / NIV at home, by increasing the motivation for using CPAP / NIV at home. The aim of the study is to assess the parents' feelings regarding the use of CPAP / NIV on day 0 (D0) and one month (D30) later in a standard group: therapeutic education (TEP) versus a group: TEP + Yapouni.

The 4 following scores have been proposed to detect OSA (Obstructive Sleep Apnea): DES-OSA, STOP-Bang, P-SAP, and OSA50. The aim of this study is to evaluate the optimal cutoff value of these four scores to detect specifically serve OSA patients with hypoxemia.

This is an exploratory study designed to evaluate the incidence of, and to quantify sleep disordered breathing following stage I Norwood reconstructive surgery. Sleep disordered breathing will be correlated with: Elevations in pulmonary vasculature resistance at the time of Stage II surgery. Risks of death

There is a possible implication of sleep apnea syndrome via night-time intermittent hypoxemia in perturbation of quality of life and tumour progression to patients with a bronchial cancer. The aim of the study is to evaluate this possibility with the help of a night record of sleep and quality of life questionnaires.

Sleep apnea is a prevalent disorder in patients with coronary artery disease. Previous studies suggested sleep apnea was associated with coronary plaque burden and future adverse cardiovascular events after percutaneous coronary intervention. In the SABOT study, the investigators used a FDA-approved portable sleep device to diagnose sleep apnea, and evaluate the relationship between sleep apnea and cardiovascular outcomes after non-urgent coronary artery bypass surgery.

The primary objective of this study is to determine the technical failure and inconclusive test rates when using the Brizzy device for mandibular movement tracking.

This study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).

Patients with type 1 diabetes have poorer glycemic control that could lead to macrovascular or neuropathic complications; in addition to an optimal treatment, prevention of diabetes complications requires to control associated risk factors, such as hypertension or dyslipidemia. Sleep apnea syndrome is a public health problem due to its high prevalence and marked morbidity and mortality, one increasingly interesting aspect is its relationship with metabolic disorders, specifically diabetes.Obstructive sleep apnea syndrome seems to be underestimated in this population. In this context, it appears to be important to estimate the prevalence of sleep respiratory diseases in patients with type 1 diabetes.
